Solution
The correct option is D Halon
Methyl bromide, halon, nitrogen oxides and chlorofluorocarbons are the potent ozone-depleting substances. These accumulate in the stratosphere and undergo photodissociation when exposed to the UV rays. The reactive chlorine and bromine react with ozone to form diatomic oxygen and molecular oxygen.A. Nitrogen oxides are released from the vehicular exhausts and industrial emissions.B. Methyl bromide was used as a fumigant.C. Halon was used as fire-extinguisher.D. Chlorofluorocarbons were used as refrigerants.Hence, the correct answer is 'Halon'.
